Zoho Integration

Complete WMS & Inventory Management on Top of Zoho

Zoho Books • Zoho Inventory • OAuth

Transform Zoho Books into a Complete WMS

Zoho Books and Zoho Inventory are popular cloud-based ERP systems for SMEs and e-commerce businesses. While excellent for accounting and order management, they lack the warehouse and shop floor capabilities needed for operational traceability.

IoTReady adds the missing layer—turning Zoho into a complete WMS with barcode/RFID tracking, automated stock movements, real-time inventory sync, and order fulfillment workflows.

OAuth Integration

Secure authentication via Zoho OAuth 2.0—no credentials stored

WMS Capabilities

Receiving, putaway, picking, packing, dispatch—all tracked in real-time

Real-Time Sync

Instant stock updates to Zoho Books/Inventory as operations happen

API Documentation: IoTReady uses official Zoho Books and Zoho Inventory APIs with OAuth 2.0. View Zoho Books API docs →

  • Quotes: Sync inventory availability for quotes
  • Notes: Add notes on order issues or delays

OAuth Scope: ZohoCRM.modules.all

OAuth 2.0 Security

IoTReady uses Zoho's OAuth 2.0 authentication—the industry-standard secure method:

  • No username/password storage—authorization via token exchange
  • Granular permissions—request only needed API scopes
  • Automatic token refresh—seamless session management
  • Revocable access—customers can revoke at any time from Zoho settings

Setup: One-time OAuth consent during integration setup. Customers authorize IoTReady to access their Zoho data via Zoho's secure authorization flow.

How Zoho Integration Works

1. OAuth Setup (One-Time)

During initial setup, customer authorizes IoTReady to access Zoho data:

  • Customer clicks "Connect to Zoho" in OTP settings
  • Redirected to Zoho OAuth consent screen
  • Customer authorizes required scopes (Inventory, Books)
  • IoTReady receives OAuth token for API access
  • Token stored securely, refreshed automatically

2. Master Data Sync

IoTReady syncs Zoho master data to OTP for validation:

  • Items (SKUs) from Zoho Inventory
  • Warehouses and bin locations
  • Sales orders and purchase orders
  • Contacts (vendors, customers)
  • Scheduled sync (hourly or real-time webhooks)

3. Warehouse Operations with Barcode/RFID

Operators use barcode scanners or RFID readers for all warehouse activities:

  • Scan incoming items → OTP validates against Zoho PO → directs putaway
  • Pick sales order → scan items → verify against Zoho Sales Order
  • Pack items → scan into shipping box → generate label
  • Cycle count → RFID bulk read → reconcile with Zoho Inventory

4. Automatic Sync to Zoho

OTP posts transactions to Zoho in real-time or batched:

  • Receiving complete → POST Inventory Adjustment (increase stock)
  • Picking complete → POST Package (mark items shipped)
  • Dispatch → PUT Sales Order (update status to Shipped)
  • Invoice trigger → POST Invoice in Zoho Books
  • Returns → POST Inventory Adjustment (return to stock)
